so what steps do i take first?

Homework Statement a 1,000 kg car coasts into a slight dip in the road. The radius of the dip is 200-m. At the bottom of the dip the speed of the car is 10 m/s. what is the magnitude and dirrection of the normal force? Homework Equations Sum of f=ma to find acceleration. The...

Tension in the cord on the bucket is equal to the gravitational force?

Thank you so much!

gravity and the normal force The normal force, gravity, friction?

i really don't know how to start it, i drew a diagram but I am not sure what to do next

176.4 cos(37)=140.9 N*u=101.34 140.9u=101.34 so u=.719

Homework Statement A 28.0 kg block is connected to an empty 1 kg bucket by a cord running over a frictionless pulley. The coefficient of static friction between the table and block is 0.320. Sand is gradually added to the bucket until the system just begins to move. a) calculate the mass of...

4.86=106.2-? so 101.34? or is there more than one other force?, Thank you for helping I'm sorry I'm really bad at physics.

5.9?

ohh, maybe how can i do it without friction though?

Homework Statement An 18.0 kg box is released on a 37.0 degree incline and accelerates down the incline at 0.270 m/s/s. Find the friction force impeding it's motion. How large is the coefficient of friction? Homework Equations Ff=uFn The Attempt at a Solution I have no idea how to...
